Overview

What is he best known for?

The fields of study he is best known for:

  • Enzyme
  • Biochemistry
  • Photosynthesis

David A. Walker mainly investigates Photosynthesis, Biochemistry, Chloroplast, Spinach and Botany. The Chlorophyll fluorescence research he does as part of his general Photosynthesis study is frequently linked to other disciplines of science, such as Oxygen evolution, therefore creating a link between diverse domains of science. His work in the fields of Biochemistry, such as Pyruvate carboxylase, Fruit Flavor and Nicotiana tabacum, overlaps with other areas such as Genetically modified tomato.

David A. Walker has researched Chloroplast in several fields, including Dihydroxyacetone phosphate, Phosphate, Fructose, Ribulose and Protoplast. His Spinach research focuses on Spinacia and how it relates to Superoxide and Reagent. His Botany research is multidisciplinary, incorporating perspectives in Carbon dioxide and Carboxylation.

His most cited work include:

  • CRITERIA OF INTACTNESS AND THE PHOTOSYNTHETIC ACTIVITY OF SPINACH CHLOROPLAST PREPARATIONS (380 citations)
  • Measurement of the ascorbate content of spinach leaf protoplasts and chloroplasts during illumination (344 citations)
  • Role of orthophosphate and other factors in the regulation of starch formation in leaves and isolated chloroplasts. (341 citations)

What are the main themes of his work throughout his whole career to date?

Photosynthesis, Chloroplast, Biochemistry, Spinach and Botany are his primary areas of study. His research integrates issues of Biophysics and Chlorophyll in his study of Photosynthesis. His work deals with themes such as Photochemistry, Carbon assimilation, Electron transport chain and Substrate, which intersect with Chloroplast.

The concepts of his Spinach study are interwoven with issues in Cytoplasm, Stimulation, Spinacia and Sucrose. His work on Plant physiology as part of general Botany research is often related to Hordeum vulgare, thus linking different fields of science. His studies deal with areas such as Analytical chemistry and Chlorophyll a as well as Chlorophyll fluorescence.

He most often published in these fields:

  • Photosynthesis (61.82%)
  • Chloroplast (52.12%)
  • Biochemistry (51.52%)

What were the highlights of his more recent work (between 1990-2009)?

  • Photosynthesis (61.82%)
  • Botany (16.97%)
  • Biochemistry (51.52%)

In recent papers he was focusing on the following fields of study:

David A. Walker focuses on Photosynthesis, Botany, Biochemistry, Ecology and Chloroplast. His Photosynthesis research is multidisciplinary, incorporating elements of Chlorophyll, Engineering physics and Photophosphorylation. His study in the field of Plant physiology and Carbon assimilation is also linked to topics like Castor beans, Isolation and Genealogy.

David A. Walker integrates Biochemistry and Genetically modified tomato in his studies. His research in the fields of Land use overlaps with other disciplines such as Rapid response, Energy and Extension. His research investigates the connection between Chloroplast and topics such as Inorganic phosphate that intersect with problems in Chlorella.

Between 1990 and 2009, his most popular works were:

  • Concerning a Dual Function of Coupled Cyclic Electron Transport in Leaves (265 citations)
  • Identification of a Specific Isoform of Tomato Lipoxygenase (TomloxC) Involved in the Generation of Fatty Acid-Derived Flavor Compounds (254 citations)
  • Biofuels, facts, fantasy, and feasibility (153 citations)

In his most recent research, the most cited papers focused on:

  • Enzyme
  • Metabolism
  • Biochemistry

David A. Walker mainly focuses on Photosynthesis, Ecology, Biochemistry, Energy and Land use. His Photosynthesis study combines topics from a wide range of disciplines, such as Ammonium, Nuclear chemistry, Nitrogen, Cytosol and Phosphate. The study incorporates disciplines such as Excited state and Biochemical engineering in addition to Ecology.

In most of his Biochemistry studies, his work intersects topics such as Hexanal.
